AUTOMOBILE TIRE RIM;

Application filed May 5,

To all vol-10m it may concern:

Be it known that I, EDGAR L. AVERA, a citizen of the United States,residing at- Fort Valley, in the county of Houston and State of Georgia,have invented certain new and useful Improvements in Automobile- TireRims; and I do hereby declare the following to be a full, clear, andeXact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to rims for automobile tires and particularly tothe type of rim involving separable arcuate segments capable of beingdisconnected to facilitate the mounting and demounting of tires andwhich may readily be restored to normal assembled relation affordingproper and adequate support for the tire mounted thereon.

A primary object of the invention isto provide an automobile rim havinga detachable rim section which is firmly secured in position tocompletethe rim by simple and ellicient means.

Another object of the invention is toprovide a strong, simple and easilymanufactured rim consisting of a few rugged parts.

A further objectot the invention is to term and relate the several partsof the rim in such manner that the manipulations of the detachable rimsection necessary to permit the mounting and demounting of tires may beeasily and quickly performed with safety and certainty of operation.

A still further object of the invention is to produce an economicallypractical rim of the type indicated which is universally applicable toall of the standard forms of wheels at present in common use.

One oi the principal features of the invention, generally stated,consists in con structing the rim with a major section. having a gaptherein for receiving a detachable l'lll] section, the latter beingprovided with a circumferential extension terminating in a stepped endwhich interlockingly engages correspondingly formed parts of the majorrim section, and the detachable rimsect-iOn and its extension beingassociated with a pivoted member so as to constitute a toggle mechanismwhich is operable to force the detachable rim section into the gap inthe major rim section.

An t e Prim y fe tu of he invention 1924. Serial No. 711,221.

consists in providing the detachable rim section with acircumferentially extending telly bridge forming apart of the togglemechanism for actuating said rim section, the telly bridge being formedwith an aperture adapted to receive a valve stem and being also providedwith a series of circumferentially spaced openings each adapted toreceive a transversely extending bolt for forming a connection with awheel, and the valve stem aperture being positioned between a pluralityof the bolt receiving openings.

Other features of invention residing in advantageous details ofconstruction and particular relations of elements will hereinafterappear and be pointed out in the claims.

In the drawings illustrated a preferred embodiment of the inventionFigure 1 is a side view of a wheel having an automobile tire rimembodying the invention applied thereto.

Figure6 is a detail plan view of a portion of one end of the major rimsection.

Figure 7 is a detail plan view of the adjacent end portions ot thedetachable rim section and telly bridge.

Figure 8 isa detail plan view '01 the end portion Off the detachable rimsection shown in Fig. 7.

The tire supporting rim comprises a major rim section 1 and adetachable. rim section 2 which is adapted to fit in between the ends 3and 4 of the major section so as to complete the rim. In order that theremovable section 2 of the rim may be assembled with and disassociatedfrom the principal rim section 1, the abut-ting ends 3 and Y arereversely stepped.

clined or beveled, while the other abutting ends a and 6, respectively,of the rim sections preferably extend radially.

Rigidly attached to the inner side of the detachable rim section 2, asby means of rivets 7, is a telly bridgeS which extends circumferentiallybeyond the ends of the removable rim section 2. The telly bridge isadapted to be received in the circumferential channel of the Well knownform of metal felly 9 with which the wheel is shown as provided.

Each of the rim sections is formed with oppositely disposedcircumferential flanges 10 for receiving a tire between them, the saidflanges being integrally united by intervening base portions 11 of therespective rim sections. The base portion 11 of the detachable rimsection 2 extends cifi' cin'nterentially somewhatbeyond the ends 6 ofthe flanges 10 so as to form a rim member extension 12 which mayadvantageously be of T shape. The base portion 11 ot the major rimsection 2 at the end 1 of said rim section is provided with acorresponding open ended Tsha ed slot 13 for receiving and inter lookingwith the headed projection 12 of the detachable rim section. Adjacentthe slot 18', but circnmferentially spaced somewhat therefrom, is a lugor'lip 14:: which is rigidly secured to the principal rim section 1. Thelug 14 is spaced from the base of the major rim section by suitablemeans, such, for example, as a lillerblock 15, the end of the lug 14sfacing the detachable rim section being disposed in. overhanging:relation to the filler 15 so as to form a pocket or recess for thereception of the end portion 1 6 of the telly bridge which projectscircumi erentially beyond the neighboring. basal extension 12 of thedetachable rim section 2.

It will be observed that the overlapping portions 12 and 16 form acircumferential extension of the detachable rim section projectingbeyond the adjacent flanges 10 of said section, the end of saidextension being formed as faces disposed in stepped relation at unequalradial distances from the center of the rim and it will also be observedthat the abutting facesot the base plate 11 and oi the s ziacing plateor filler 15 The stepping at these cooperating parts, together with theoverhanging relationship of the telly bridge engaging lug let,- ensuresthat the manipulations of the detachable rim section necessary to permitthe mounting and demounting' of: tires may be performed with ease andcertainty without danger of any of the parts assuming improperrelations, and this construction also results in firmly securing theneighboring ends or the rimsection' against relative radial ortransverse movement both inwardly and: outwardly. It will be appreciatedalso that the entry of the headed tongue 12 into the corresponding slot13 of the major rim section prevents circumferential separation of theserim elements.

The circumferentially extending lfelly bridge is preferably formed froma suitable flat blank bent into channel form so as to provide spacedflanges 17 receivable in the channel of the wheel telly 9. The baseportion 18 of the telly bridge is provided beyond the end 5- of thedetachable rim section with an aperture or recess 19 to receive andpermit the operation of a toggle mem her or bar 20 as well as the lugmembers 21 and 22, respectively, carried by the major rim section 1adjacent the end 5; thereof. The toggle member 20- is pivotally mountedbetween the circumferential flanges 17 of the "telly bridge 8 by meansof a suitable pivot pin 23 passing through said flanges somewhatinwardly of the base portion' 18 ofthe bridge. As is well illustrated inFigs. 3 and 4-, it results from this con struction that when the rimsections 1 and 2 are in assembled relation the tog le member 20 extendscircumterentially from its pivot pin away from the end 3 of theprincipal rim section, and the studs or lugs 21 and 22 engage andinterlock with the walls of the aperture 19 in the telly bridge so as tolock the nei hboring ends 3 and 5 of the respective rim sections againstlateral movement. v

Outward radial movement of the detachable rim section 2 beyond itsproper assem bled position is prevented by the portion of the tellybridge 8 which overlaps the neighboring base portion 11 of the major rimsection 1, while any possible inward radial movement of the detachablesection 2 may be ad-i antagcously' prevented by means of the lockingmember 24' adapted to engage and interlock with the grooved stud orprojec'tion 22' carried by' the rim member 1. The locl'i-ing'member 2iis preferably slidably mounted upon the end of the telly bridge, beingslotted as at 25 to permit it to slide back and torth on a rivet 2G bywhich it is secured to the said. bridge 8. The end 27 of the lock 24which engages the stud 22 of the rim is recessed or bifurcated so as toembrace the stud 22 within the groove or channel thereof, thus enablingthe locking member to interlock with the said stud.

The detachable rim section 2 and the connected telly bridge 8,together-with the bar 20 pivotally mounted upon the latter, coustitute atogg'le mechanism enabling the dctachable rim section to be easily andconveniently forced to assembled relation in the gap of the majorsection 1 so as to complete the rim. In order to ensure againsl slippagewhen the toggle mechanisi'n is being operated to force the detachablerim sec-- tion 2 into assembled position,- the free end 28 ot bar 20 mayadvantageously be torked or slotted so as to straddle a portion of thelug 22 upon the rim section 1 which forms an abutment tor the pivotedmember 20 during the operations of bringing the detachable rim sectioninto assembled position or disassociating it from the major rimsection 1. i

The base 18 ot the telly bridge. 8 is provided intermediate its endswith an opening 29 for receiving the valve stem ot a tire, and one otthe rim sections is provided with a corresponding registering opening 30tor a similar purpose. Each of the circumterential flanges 17 ot thetelly bridge is tormed with a plurality of corresponding oppositelydisposed openings 31 adapted to receive a transversely extending rim bolsuch as 32, tor torming a connection with the telly 9. The valve stemopening 29 in the base ot the telly bridge is circumferentiallyinterposed between a plurality ot the bolt receiving openings 31 andthey are so positioned with respect to said valve stem opening as to besuitable tor receiving a rim bolt adapted to cooperate with any standardtorm ot wheel now in general use, By torming the telly bridge with avalve stem receiving opening it is possible to produce economically anentirely practical demountable rim adapted tor universal application toall common makes ot wheels.
